A Preble County Sheriff’s deputy, who was working as a school resource officer at National Trail Schools, was arrested after allegedly having a relationship with a student.

Deputy Mason Williams was arrested Friday and charged with one count of sexual battery, tampering with evidence, and dereliction of duty.

Lanie Shumard told News Center 7 that her kids go to National Trail Schools. She listened as Preble County Sheriff Mike Simpson explained that Williams was placed on administrative leave after having a consensual relationship with an 18-year-old student.

“He is an authority figure, so it’s kind of concerning,” she said.

As Simpson announced on Saturday, he asked the Montgomery County Sheriff’s Office to handle the criminal and internal affairs investigation into Williams.

“In a situation like this, with the allegations being what they are and the evidence that could be uncovered, I think it’s certainly better that have an outside agency come and take a look at it,” Montgomery County Sheriff’s Office Chief Deputy Matt Haines told News Center 7.

Haines said outside eyes show the Preble County Sheriff wants transparency and trust in the investigation.

News Center 7 reached out to the school district for a comment on the allegations. They sent a statement that was sent to district families. It said in part:
